With the holiday weekend approaching, Paramount Pictures has already unleashed Terminator: Genisys in theaters. It’s a mind-numbing, time travel action adventure that doesn’t measure up to the greatness of James Cameron’s The Terminator or T2: Judgment Day, but runs circles around Terminator 3: Rise of the Machines and Terminator: Salvation.

But if you haven’t kept up with the Terminator franchise over the past few decades, you can catch up on Terminator history in 10 minutes with a new retrospective video that begins with The Terminator back in 1984 and moves up through Terminator: Salvation from 2009. It tells you everything you need to know, though it doesn’t explain the best way to deal with all the time travel that’s been happening.

As you can see above, the video runs through a brief history of The Terminator franchise, including some tidbits about the making of each of the films. Cool tidbits (that hardcore Terminator fans probably already know) include the fact that Arnold Schwarzengger was originally interested in the role of Kyle Reese, but ended up becoming more fascinated with the title villain role instead. Who knows how the franchise would have turned out if Schwarznegger hadn’t take the role of The Terminator instead.

There’s also talk about the state of the art special effects created in 1990 to bring the T-1000 to life in Terminator 2: Judgment Day (see a more detailed account of that in a post from earlier this week). Thankfully, most of the time is dedicated to the first two films, with only two minutes used to cover Terminator 3 and Terminator: Salvation.
